2010-12-13x86: Check tsc available/disabled in the delayed init functionThomas Gleixner
The delayed TSC init function does not check whether the system has no TSC or TSC is disabled at the kernel command line, which results in a crash in the work queue based extended calibration due to division by zero because the basic calibration never happened. Add the missing checks and do not touch TSC when not available or disabled. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: John Stultz <johnstul@us.ibm.com>

2010-12-12ipv4: Don't pre-seed hoplimit metric.David S. Miller
Always go through a new ip4_dst_hoplimit() helper, just like ipv6. This allowed several simplifications: 1) The interim dst_metric_hoplimit() can go as it's no longer userd. 2) The sysctl_ip_default_ttl entry no longer needs to use ipv4_doint_and_flush, since the sysctl is not cached in routing cache metrics any longer. 3) ipv4_doint_and_flush no longer needs to be exported and therefore can be marked static. When ipv4_doint_and_flush_strategy was removed some time ago, the external declaration in ip.h was mistakenly left around so kill that off too. We have to move the sysctl_ip_default_ttl declaration into ipv4's route cache definition header net/route.h, because currently net/ip.h (where the declaration lives now) has a back dependency on net/route.h Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-13sh: Enable deprecated IRQ chip APIs for MFD and GPIOLIB drivers.Paul Mundt
There are still quite a number of MFD and GPIO expander drivers that are using the old irq_chip APIs that haven't had a chance to update during the .37 cycle, resulting in allyes/modconfig errors on some configurations. Mark Brown has done most of the legwork to get these fixed up in .38, so this should just be a .37 stop-gap that we can drop at the end of the .38 merge window.

2010-12-12ARM: 6528/1: Use CTR for the I-cache line size on ARMv7Catalin Marinas
The current implementation of the v7_coherent_*_range function assumes that the D and I cache lines have the same size, which is incorrect architecturally. This patch adds the icache_line_size macro which reads the CTR register. The main loop in v7_coherent_*_range is split in two independent loops or the D and I caches. This also has the performance advantage that the DSB is moved outside the main loop.

2010-12-12ARM: 6527/1: Use CTR instead of CCSIDR for the D-cache line size on ARMv7Catalin Marinas
The current implementation of the dcache_line_size macro reads the L1 cache size from the CCSIDR register. This, however, is not guaranteed to be the smallest cache line in the cache hierarchy. The patch changes to the macro to use the more architecturally correct CTR register.

2010-12-12drivers/net: don't use flush_scheduled_work()Tejun Heo
flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

Also, the MAX_RX_DESC_1 multiply the max number of rings by max number of blocker per ring by 127, but the driver does the same calculation with 127+1.
